To all whom it may concern:

Be it known that I, Grocer ADELMO, a subject of the King of Italy, and aresident of Spring Valley, in the county of Bureau and State ofIllinois, have invented a new and useful Improvement in ElectricVibrators for Razors and the like, of which the following is a full,clear, and exact deprovide a razor operating device in which the razorclamp may be removed therefrom and the ordinary type of vibratorappliance substituted. 1

A further object of my invention is to provide a device of thetypedescribed in which particular novel means is employed for housing theinternal mechanism to assure against unintentional and discordantvibration.

A further object of my invention is to provide a device of the typedescribed in which the'internal mechanism for vibrating the razor clampis housed in an insulating casing, thereby insulating all of theelectrical parts from the hand of the operator, and also providing aheat insulating medium about the internal mechanism.

Other objects and advantages will appear in the following specification,and the novel features of the invention will be particularly pointed outin the appended claims.

My invention is illustrated in the accom panying drawings, forming partof this application, in which Figure 1 is a front'elevation of an embodiment of my invention,

Figure 2 is a partial side elevation of the mechanism illustrated inFigure 1,

Figure 3 is a top lan view of the mechanism illustrated in igure 1,

Figure t is a front elevation of a part of the mechanism illumrated in-Fi ure 1', a portion of the casing being remove therefrom, and

Figure 5 is an enlarged sectional view along the'line 5-5 of Figure 4.

In carrying out m invention I make use I of a casing comprising twocooperating parts A and B. These parts are constructed of moldedcomposition, such as bakelite or other Well known compositions, havinginsulating properties. The casing is narrowed as shown at 1 upon itsside walls so as to facilitate the holding of the casing in the hand ofthe operator in such a manner as to preclude any slipping of the devicedue to its inherent vibratory properties. The casing is further providedwith vents 2 arranged in symmetrical groups, (see F igure 1) through themajor walls of the cooperating parts A and'B. The purpose of these ventsis to permit air to circulate through theinternal mechanism of thedevice and prevent overheating of the mechanism. i

The mechanism employed for imparting vibratory motion to the razorclamping mechanism consists in a substantially Ushaped laminated corehaving protrusions 4 at each end of the rearward part or heel of thecore, (see Figure 4). These protrusions 4 form an ingenious means forpreventing unintentional movement of the core 3 relative to the casing.This guard against movement of the core is brought about by theprovision of a recess R in the adjacent side Walls of the parts A and Bhaving the shape ofthe rearward portion of the core 3, includingcavities C for receiving protrusions 4. In this manner, the core 3 issecurely clamped against movement when the parts A and B are securedtogether as by means of binding screws 5, provided for that purpose.

' Each of the branches 6 and 7 of the core 3 has wound thereupon a coilof current conducting Wire 8. These coils 8 are connected in series withone another at 9, and one of the leads 10 therefrom is connecteddirectly with a conductor 11, the other end of which is connected with asuitable attachment plug, (not shown). This attachment plug is oftheordinary type, such as used for stand lamps, flat irons, and the like.The opposite lead 12 of the coils 8 is connected to one terminal post 13of the switch 14. The opposite terminal post 15 of the swltch isconnected to the remaining connection wire 16 wl1ich is in turnconnected with the aforesaid attachment plug.

The connecting wires 11 and 16 are both run through a flexible lead 17formed of a coil of tightly wound spring wire, which 1s projectedthrough registering channels 18 in the parts A and B, at the lower endthereof. The inner end of the spring lead member 1'? is enlargedsomewhat to prevent its movementexteriorly of the casing.

The arn'iature upon which the razor supporting clamp is supported iscompri ed in a band of magnetizable metal 19 having one end thereofprojected through registering channels ot' the parts A and B, and issubstantially angular in cross section. The armature 19 is arranged tolie directly in front of the branches 6 and 7 of the core 3, but notnormally touching these branches. The lower end of the armature 19 isbent and is arranged to lie directly upon the innermost side of thelower wall of the parts A and P) as shown at :22. A binding plate isdisposed upon the outer side of the lower wall of the parts A and B inregistration with the part of the armature 19. and machine screws 2 areprojected through the plate 2 the lower walls of the parts A and l3, andare threaded directly into the portion 22 of the armature 19. Thisparticular means for mounting the armature 19 is one which I deem oi.particular importance. since it provides a rigid su portt'or the lowermost end of the armature, which is an armato re vibrating at anexceedingly high period. and also serves to eli ectively clamp thelowermost portions of the parts A and B against movement apart from oneanother, thereby doubly assuring the separation of. the casing at thispoint. which might occur if some such means as justdescribed were notdevised.

It is well to note at this time that my improved razor operating deviceis intended for use upon the ordinary alternating current service line.in wl h the frequency of alternations is oidinarily fixed at 60 cyclesper second. It will therefore be apparent that the period of vibrationof the armature is most exceedingly nigh, and that rigidity in mountingthe internal parts is of utmost importance, particularly in a device ofthis type.

The switch 14 is more clearly shown in Figure and the internal workingparts of the device are mounted upon the disc 14-. Th s disc 14 isarranged to be partially re ce ed within an enclosure formed by theProvision of an inwardly extending annular rl nge 25 on the innermostwall of the part An opening 26 is provided through the Wall of the partA in registration with the a. :is of the annular tlange 25 to permit theprojection of the stem 27 of the switch mechanism mounted upon the disc14. The outermost end of the stem 27 has a knob 28 thereupon. the switchbeing disposed exte- -e'iorly of th :asing. and may be manually operatedby the tu :lng of the knob so as to rotate the commi ator 29, forming apart of the aforementioned switch mechanism.

My improved electric vibrator is primarily intended for operating arazor for shaving, yet the device may be used with equal ad vantage forthe operation of any one of the many well known vibrator appliances,such as cups, balls, combs and the like, for the purpose of facial andscalp massage. The following is a description of one form of razorholding device which, while shown in this application, claimed in mycopending application Serial No. 744,298.

The razor holding clamp which is arranged for disposition upon theangular portion 21 ot' the armature 19 consists in a body member 90having an angular loop-shaped member 31. at one end thereot which isarranged to fit over the angular part 21 of the arn'iature. A. thumbscrew 32 projected through the body member 30 adjacent to the loopportion 31. provides means by which the loop 31 may be slightlycontracted, and in this manner securely clamps the body member 30 uponthe arn'iature 19.

The body member 30 is provided with :1 depending member arranged toyieldably engage with the handle 33 of the ordinary type of razor Thisdepending member consists in a pair of spring clamps carried by the bodymember 30 and disposed at a slight angle with respect to the axis of thepart 21 ot the vibrator 19. A separator 36 is disposed between thespring clamping meu'ibers 35 and is arranged to extend slightly belowthe lowermost ends of these members. Toe lmvermost ends of the membersare dished outwardly as shown at 37, so that the split handle 33 mayeasily be moved beyond the lowermost ends of the spring clamping members35 when placed astride the separator 36 in the manner shown in Figure 2.The clamping members func tion solely to yieldably hold the handle 33 ofthe razor against both longitudinal and lateral movement relative tothebody member 30 of the clamping mechanism.

Means for supporting the blade 38 ot the razor 3-4; when first insertedin a suitable guard 39 is provided as follows: A strap -10 is hingedlymounted at all to the body member 30 in such a manner as to permit thestrap 40 to be moved to the position shown in full lines in Figure 1, orto the position shown in dotted lines. In both cases the strap 4-0 liesin a plane substantially parallel with the separator 36.

This strap 4-0 has disposed at its outermost end a spring pressed clamp42, the worl: engaging part 43 of which is in turn pivotally connectedto the clamping member 4-2 so as to completely conform ith the irregularconfiguration of the neck of the razor 34. It is therefore evident thatthe razor blade 38, together with its guard 39 may be firmly securedagainst movement upon the body member of the clamping various parts ofthe device, the operation thereof may be readily understood. The personusing the device will first manually place the guard 39 between thestrap 40 and the spring pressed clamping member 42 so that the blade 39is securely fixed against movement relative to the strap, and thereforeto the body member 30.

The strap 40 is then hinged to the position shown in full lines shown inFigure 1 or to the position shown in dotted lines, de-

ending upon which side of the face is to lie shaved, and the blade 30 ishinged upwardly so that the split portion thereof may lie astride theseparator 36 and be received between the spring pressed clamping members35 which will securely hold the handle against movement bothlongitudinally and laterally. The switch mechanism operated by the knob28 is then closed so as to permit current to flow through the coils 8,thereby causing a magnetic field about the branches 6 and 7 of the core3, and consequently causing the exceedingly high vibratory movement,which movement in turn will be imparted to the blade 38 and move theblade laterally. The blade is then moved over the face in precisely thesame manner as though the razor operating device were not employed,except that a swift stroke of the razor is not necessary.

Obviously my improved vibrating mechanism may be used for the purpose ofsupporting a suitable clamping device upon the stem 21 for holdingordinary types of safety razor, mechanical vibratory appliance or thelike, without in any way departing from the spirit and scope of theinvention.
